The body may have a main portion having an arch-shaped central portion, a first side portion extending from a first end of the central portion, and a second side portion extending from a second end of the central portion. The body may further include a first wedge portion provided on a bottom surface of the first side portion, and a second wedge portion provided on a bottom surface of the second side portion. Each of the first wedge portion and the second wedge portion may have a varying thickness. ## Claims ### Claim 1 An oral device comprising a body including: a main portion having an arch-shaped central portion, a first side portion extending from a first end of the central portion, and a second side portion extending from a second end of the central portion; a first wedge portion provided on a bottom surface of the first side portion; and a second wedge portion provided on a bottom surface of the second side portion, wherein each of the first wedge portion and the second wedge portion has a varying thickness. ### Claim 2 (depends on 1) The oral device of claim 1, wherein each of the first wedge portion and the second wedge portion has a minimum wedge thickness at a posterior end thereof, and a maximum wedge thickness at an anterior end thereof. ### Claim 3 (depends on 2) The oral device of claim 2, wherein the wedge minimum thickness is between 10% and 100% of the maximum wedge thickness. ### Claim 4 (depends on 1) The oral device of claim 1, wherein each of the first wedge portion and the second wedge portion has a wedge portion width, each of the first side portion and the second side portion has a side portion width, and the wedge portion width is less than the side portion width. ### Claim 5 (depends on 4) The oral device of claim 4, wherein the wedge portion width is between 20% and 50% of the side portion width. ### Claim 6 (depends on 1) The oral device of claim 1, wherein each of the first wedge portion and the second wedge portion has a wedge portion length, each of the first side portion and the second side portion has a side portion length, and the wedge portion length is less than the side portion length. ### Claim 7 (depends on 6) The oral device of claim 6, wherein the wedge portion length is between 50% and 100% of the side portion length. ### Claim 8 (depends on 1) The oral device of claim 1, wherein at least one ridge is formed on each of a bottom surface of the first wedge portion and a bottom surface of the second wedge portion. ### Claim 9 An oral device comprising a body having an inner surface configured to receive one of upper teeth or lower teeth of a user and a bottom surface configured to face another one of the upper teeth or the lower teeth of the user, the body including: a main portion having an arch-shaped central portion, a first side portion extending from a first end of the central portion, and a second side portion extending from a second end of the central portion; a first wedge portion provided on a bottom surface of the first side portion; and a second wedge portion provided on a bottom surface of the second side portion, wherein each of the first wedge portion and the second wedge portion has an anterior end, positioned closest to the central portion of the main portion, and a posterior end, positioned farthest from the central portion of the main portion, and wherein each of the first wedge portion and the second wedge portion has a varying thickness from the posterior end to the anterior end. ### Claim 10 (depends on 9) The oral device of claim 9, wherein each of the first wedge portion and the second wedge portion has a minimum wedge thickness at the posterior end, and a maximum wedge thickness at the anterior end. ### Claim 11 (depends on 10) The oral device of claim 10, wherein the wedge minimum thickness is between 10% and 100% of the maximum wedge thickness. ### Claim 12 (depends on 9) The oral device of claim 9, wherein each of the first wedge portion and the second wedge portion has a wedge portion width, each of the first side portion and the second side portion has a side portion width, and the wedge portion width is less than the side portion width. ### Claim 13 (depends on 12) The oral device of claim 12, wherein the wedge portion width is between 20% and 50% of the side portion width. ### Claim 14 (depends on 9) The oral device of claim 9, wherein each of the first wedge portion and the second wedge portion has a wedge portion length, each of the first side portion and the second side portion has a side portion length, and the wedge portion length is less than the side portion length. ### Claim 15 (depends on 14) The oral device of claim 14, wherein the wedge portion length is between 50% and 100% of the side portion length. ### Claim 16 (depends on 9) The oral device of claim 9, wherein at least one ridge is formed on each of a bottom surface of the first wedge portion and a bottom surface of the second wedge portion. ### Claim 17 A method of manufacturing an oral device, the method comprising: applying heat and pressure to a moldable material around one of an impression of upper teeth or an impression of lower teeth of a user, forming a molded structure; trimming excess material, of the moldable material, from the molded structure forming a body of the oral device, the body including a main portion having an arch-shaped central portion, a first side portion extending from a first end of the central portion, and a second side portion extending from a second end of the central portion; forming, using the excess moldable material and/or additional moldable material, a first wedge portion and a second wedge portion, each of the first wedge portion and the second wedge portion having a varying thickness; and attaching the first wedge portion to a bottom surface of the first side portion, and the second wedge portion to a bottom surface of the second side portion. ### Claim 18 (depends on 17) The method of claim 17, wherein, in the forming of the first wedge portion and the second wedge portion, the first wedge portion and the second wedge portion are formed in layers of the excess moldable material and/or the additional moldable material, with a base layer having a greatest length, and each subsequent layer having a shorter length than a previous layer. ### Claim 19 (depends on 17) The method of claim 17, wherein, in the attaching, at least one of an upper surface of the first wedge portion and the bottom surface of the first side portion, and at least one of an upper surface of the second wedge portion and the bottom surface of the second side portion are heated, the upper surface of the first wedge portion and the bottom surface of the first side portion are pressed together, and the upper surface of the second wedge portion and the upper surface of the second side portion are pressed together. ### Claim 20 (depends on 17) The method of claim 17, wherein each of the first wedge portion and the second wedge portion has a minimum wedge thickness at a posterior end thereof, and a maximum wedge thickness at an anterior end thereof.
